For the mean time I had to hold the memory riser cards up by using so electrical tape see picture below. I wanted to get some extra performance out of this Mac Pro to put it in a closer category with my 2. Most were being advertised as an upgrade kit for the original Mac Pro. I decided to look at some similar processors and settled on the Xeon X This processor is literally the exact same as the X but runs at the lower clock speed of 2.

Mac Pro (Early 2008) - Technical Specifications

The upgrade process went smoothly!! The new geekbench score blew the old one out of the water! All in all, even though this Mac Pro is close 8 years old now, it still is a very fast machine!! Skip to content I know this is a couple weeks late, but for those wondering, the OS X I should be able to put the new processors in this weekend sometime. Stay tuned for an update!
